Command CodeSign failed with a nonzero exit code

Hello, I'm attempting to compile DeSmuME from source using the instructions provided in the wiki. When I select the scheme DeSmuME (OS X App -- Latest Xcode) and Build For -> Profiling as described in the wiki, I get this error: Command CodeSign failed with a nonzero exit code. It also reports 'bundle format unrecognized, invalid, or unsuitable'.

I have no experience with Xcode, and I don't know how to correct this so that the app builds successfully. I can compile Dev+ and Debugger builds, but they crash as soon as I try to open them.

If Rogerman or someone else could provide new compiled Mac builds, I would be very grateful. Also I would like to point out that the compiled builds are not found at /desmume/src/frontend/cocoa/build/Release as described in the wiki, instead they are found at /Library/Developer/Xcode/DerivedData/DeSmuME/Build/Products/Release. Someone should update the wiki with this information as it is quite misleading as things stand.
